Hi. I love this forum and have received a lot of good information reading through the other posts. Now I’m looking for some guidance on a rough idle situation.
The Details: I can start my car first thing in the morning and drive it for a while(20 miles / 30 min to work), shut it off, and if I turn it right back on it starts and runs fine. It will also start and run fine when I get into the car after work and drive it home. Now here is where I will notice the issue. After I shut the car off for anywhere from 5-40 minutes and then try to restart the engine it will start, but it sputters and idles really low and really rough and will even die on me if I don’t hold my foot on the gas at about 2000 rpm for 10-15 seconds. After this it is still running very rough, but I can drive it and after a few minutes it’s all smoothed back out again and running fine.
For various issues and just maintenance I’ve already replaced the MAF sensor (Got a cheap one, but it runs the same with the old and the new, and with it unplugged), I’ve replace the front Oxygen sensor, the plugs and wires, the radiator was flushed last summer, and I installed a new water pump this winter.
This has been going on for over a year now and I can’t handle it anymore I need some help figuring this out.
Also, I do have a code that is being thrown. P0171. I haven’t been able to find the leak yet, but it is pretty intermittent. It will come on for a day then go away for 2 days. Then it will come back for another few days.
Thanks!
